STR750-EVAL
Evaluation board
Introduction
The STR750 evaluation board (STR750-EVAL) is a complete, development platform for STMicroelectronic’s
ARM
®
core-based STR75xF microcontrollers. Based on a cost effective, flexible and open design, it allows easy demonstration of STR75xF capabilities and enables rapid evaluation of the microcontroller’s peripherals and other features.
It includes the high performance STR750F microcontroller, which is based on the ARM7TDMI-S core and includes USB 2.0 compliant port with full speed data transmission, CAN 2.0A/B compliant interface, 3 UART channels, internal Flash and internal SRAM memory.
The STR750-EVAL features a complete range of connectors and hardware features for developing applications based on STR75xF peripherals including motor control, USB and RS232 connectors, microphone, speaker, joystick, and LCD display.
The STR750-EVAL uses a JTAG standard interface to connect to your host PC via any of a range of in-circuit emulators (ICE) for ARM core-based microcontrollers.

STR750-EVAL 1 Getting Started
Your STR750-EVAL is designed with a full range of hardware features that will help you rapidly evaluate microcontroller peripherals and develop your own applications. Descriptions of
hardware features and configurations are provided in
Chapter 2
.
Demonstration software is preloaded in the board’s flash memory for easy demonstration of device peripherals in stand-alone mode. For more information refer to the demonstration software getting started.
Your STR750-EVAL is also designed for use as an application development platform and reference design, and supports connection to a full range of in-circuit debugging tools and integrated development environments.
To start using your STR750-EVAL evaluation board for application development, you will have to set up your development tools and connect to the STR75xF.
1. Connect to your STR750-EVAL via the 20-pin JTAG connector.
2. Power up the evaluation board.
The board can be powered by
5V from either the jack for external power supply, USB connector, or a daughter board.
For additional configuration
Section 2.1
.
3. Connect to the device from the debugging software on your host PC.

The STR750-EVAL evaluation board is designed to be powered by a 5V DC power supply and is protected from incorrect power supply by a polymer enhanced Zener diode (polyzen, U19) which shuts out the power source if overvoltage occurs. If overvoltage occurs, the power supply must be disconnected from the board and then reconnected in order to reset the polyzen.
It is possible to configure the evaluation board to use any of the following three sources for the power supply:
●
5V DC power adapter connected to the power supply jack (CN3, or PSU for Power
Supply Unit on the silk screen).
● 5V DC power with 500mA limitation via the USB type-B connector (CN2, or USB on the silk screen).
●
5V DC power from the daughter board extension connectors (CN6 and CN7, DTB for
Daughter Board on the silk-screen).
●
●
You can power the ARM7TDMI-S core, SRAM, and Flash of the STR750Fx using one of two power supply sources:
Internal power supply generated by internal Main Voltage Regulator.
External power supply generated by external 1.8V voltage regulator U4 on the board
STR750-EVAL 2 Hardware layout and configuration
The power supply is configured by setting the related jumpers, JP1, JP3, JP4, JP5 and JP6 as
Table 1
.
Table 1.
Power jumpers
Jumper
JP1
Description
Selects one of the three possible 5V DC power supply sources:
For Power supply jack (CN3) to the STR750-EVAL only, JP1 is set as shown to the right:
The daughter board must have its own power supply connected.
(Default setting)
For Power supply jack (CN3) to both STR750-EVAL evaluation board and a daughter board connected to CN6 and CN7, JP1 is set as shown to the right:
The daughter board must not have its own power supply connected.
For power supply from the daughter board connectors (CN6 and
CN7), JP1 is set as shown to the right:
For power supply from USB (CN2), JP1 is set as shown to the right:
If a daughter board is connected on CN5 and CN6, it must have its own power supply connected.
JP3
JP4, JP5,
JP6
Enables consumption measurement of STR75xF 3.3V VPLL, VADC and CPU_3V3.
Default setting: Fitted
Note: The Potentiometer (RV2) is also connected to VADC. As a result, measurements of the consumption of the STR75xF include the consumption of the potentiometer (~330 µA).
To determine the actual consumption of the STR75xF either subtract
330 µA from the consumption measurement, or remove (un-solder) the potentiometer from the board.
1.8V power can be provided externally or internally depending on the configuration of the jumpers JP4, JP5 and JP6:
●
For 1.8V power supply from the external regulator U4 to the STR750Fx, jumpers JP4,
JP5 and JP6 should all be fitted. In this mode, JP5 and JP6 can be used for consumption measure of V18BKP and V18 respectively.
●
For 1.8V power supply from the internal Main Regulator, jumpers JP4, JP5 and JP6 should not be fitted.
Caution: Do not use configuration patterns of JP4, JP5 and JP6 other than the two described above.
Default setting: Not fitted
The LD1 LED is lit when the STR750-EVAL evaluation board is powered correctly.

STR750-EVAL 2 Hardware layout and configuration
STR750-EVAL evaluation board supports induction motor control via a 34-pin connector CN1, which provides all required control and feedback signals to and from a motor power-drive board. Available signals on this connector include emergency stop, motor speed, 3-phase motor current, bus voltage, Heatsink temperature from the motor drive board and 6 channels of
PWM control signals going to the motor drive circuit.
Motor current sampling is enabled by setting jumper JP7.
Table 6.
Motor control jumpers
Jumper Description
JP7
Motor current sampling operation is enabled when JP7 is fitted (P1.08 connected to
P0.29). The I/O pins P1.08 and P0.29 are disconnected and can be used by a daughter board when JP7 is not fitted.
Default setting: Fitted
2.10 RTC
A 32KHz crystal X1 is available for the embedded RTC inside the STR750Fx.
2.11 USB
STR750-EVAL evaluation board supports USB 2.0A/B compliant full speed communication via a USB type-B connector (CN2). The evaluation board and daughter board can be powered from this USB connection at 5V DC with a 500mA current limitation.
Two clock sources are available for USB:
●
●
PLL generated clock from the STR750Fx
External oscillator U7
USB Connect/Disconnect Simulation
allows the application software to simulate the connection or disconnection of a USB apparatus to connector CN2 of the STR750-EVAL. This feature is implemented by connecting P0.09 of the STR75xF to the transistor that controls the connection of the USB 1.5K pull-up resistor (R6) on the USB_D+ line. The
USB Connect/Disconnect
Simulation
feature is enabled or disabled by setting JP2 as shown in
Table 7
.
Table 7.
USB Connect/Disconnect Simulation
Jumper Description
JP2
When JP2 is set as shown to the right,
USB Connect/Disconnect
Simulation is disabled. In this case, the USB 1.5K pull-up resistor is connected to the USB_D+ line and P0.09 is not use for USB.
When JP2 is set as shown to the right, USB Connect/Disconnect
Simulation is enabled. P0.09 of the STR75xF is connected to the transistor that controls the connection/disconnection of the USB 1.5K pull-up resistor
(R6) on the USB_D+ line.
When
USB Connect/Disconnect Simulation is enabled, by default the
USB 1.5K pull-up resistor
(R6) is in a “disconnect” state (i.e. as if no
USB apparatus were connected to CN2).
(Default setting)

This section provides design schematics for the STR750-EVAL key features, which are provided to help users implement these features in their own application designs. Schematics are provided for:
STR750F microcontroller connections (
Power supply (
Figure 16
UART connectors (
Figure 17
USB and CAN connectors (
Figure 18
)
Audio record and playback features (
JTAG and motor control connectors (
Figure 21
Figure 15
Figure 19
Figure 20
)
Schematics have versions, as do major versions of the evaluation board. Schematic version numbers are made up of a letter-number combination (e.g. A.1, A.2, B.1, B.2, ...), which is found in the information block on each schematic page. In these version numbers, the letter indicates the version of the evaluation board that the drawings correspond to, where as the number indicates the revision of the schematics for a given version of the evaluation board.
One (1) indicates that the schematics for the specified board are in their initial version (have not been revised).
Figure 14. Find the version of your evaluation board
Letters found in the information blocks on the evaluation board indicate the board’s version (this example shows version B of the evaluation board MB469).
